[0002] Channel risk areas refer to specific areas in the channel that are potentially dangerous or risky to ships due to natural factors (such as shoals, rocks, bad weather, etc.) or human factors (such as docks, underwater buildings, etc.). my country's economic development has promoted the increase of cross-river bridges in urban agglomerations along the river and the diversification of inland waterway regulation buildings. Freight terminals are densely distributed, ship types are diverse, the density of ships is high during the day, and the background lighting is complex at night. These factors together constitute the risk areas of inland waterways, leading to a sharp increase in the demand for safe navigation supervision services.

[0004] Usually, the ship's cockpit is equipped with a VHF radio and AIS equipment, and the driver obtains relevant information by using the VHF radio and watching the AIS equipment. In recent years, the advancement of technologies such as artificial intelligence, big data and cloud computing has further promoted the in-depth application of AIS systems and video imaging technologies in inland waterway supervision, forming a unique application-driven and problem-oriented system. Although inland waterway supervision has made certain progress, there are still deficiencies in services, especially in risk areas of inland waterways. In this case, quickly and effectively conveying risk warning information to the driver of the designated ship has become a key link in the inland waterway risk area supervision system. Only by solving this problem can the user's perception of waterway risk areas be improved, and ultimately the goal of improving the inland waterway navigation safety assurance service capabilities can be achieved.

[0029] The microprocessor of the waterway risk area supervision device has a timer Timer0 in the microprocessor, which interrupts once at the millisecond level to provide supervision services for the inland waterway risk area.

[0030] After receiving a packet of protocol data output by the AIS receiving module, the microprocessor of the waterway risk area supervision device unpacks and parses it according to the protocol to obtain the MMSI number, data time, longitude, and latitude information of the ship. Subsequently, the microprocessor matches the longitude and latitude data of the ship with the longitude and latitude data of the Z risk area control points in the table Dic_RiskZone one by one to check whether the ship is located within the Z risk areas. If the ship is within the i-th (i < Z) risk area, the MMSI number, data time, longitude data, latitude data, parameter 1, and i of the ship are saved to the fields Ship_ID, DataTime, XY_X, XY_Y, DataSource, and Zone_No of the table Ship_XY, and the timer Timer0 is started; otherwise, if it is not within the Z risk areas, the MMSI number, data time, longitude data, latitude data, parameter 1, and (Z + 1) of the ship are saved to the corresponding fields Ship_ID, DataTime, XY_X, XY_Y, DataSource, and Zone_No of the table Ship_XY.

[0031] After receiving a packet of protocol data from the machine vision module, the microprocessor of the waterway risk area supervision device unpacks and parses the name, data time, longitude data, and latitude data of the ship according to the protocol. Then, the microprocessor matches the longitude and latitude data of the ship with the longitude and latitude data of the Z risk area control points in the table Dic_RiskZone one by one to check whether the ship is located within the Z risk areas. If the ship is within the j-th (j < Z) risk area, the name, data time, longitude data, latitude data, 2, and j of the ship are saved to the fields Ship_ID, DataTime, XY_X, XY_Y, DataSource, and Zone_No of the table Ship_XY, and the timer Timer0 is started; otherwise, if it is not within the Z risk areas, the name, data time, longitude data, latitude data, 2, and (Z + 1) of the ship are saved to the fields Ship_ID, DataTime, XY_X, XY_Y, DataSource, and Zone_No of the table Ship_XY.

[0032] After receiving a packet of protocol data from the radar monitoring module, the microprocessor of the waterway risk area supervision device unpacks and analyzes it according to the protocol. After obtaining the digital serial number, data time, longitude data, and latitude data of the ship, it matches the longitude data and latitude data of the ship with the longitude data and latitude data of the Z risk area control points in the table Dic_RiskZone one by one to check whether the ship is located in these Z risk areas. If the ship is located in the k-th (k < Z) risk area, its digital serial number, data time, longitude data, latitude data, 3, and k are saved into the fields Ship_ID, DataTime, XY_X, XY_Y, DataSource, and Zone_No of the table Ship_XY, and the timer Timer0 is started; otherwise, if it is not in any of the Z risk areas, its digital serial number, data time, longitude data, latitude data, 3, and (Z + 1) are saved into the fields Ship_ID, DataTime, XY_X, XY_Y, DataSource, and Zone_No of the table Ship_XY.

[0033] When entering the timer Timer0 interrupt service routine, the microprocessor of the waterway risk area supervision device starts the supervision service, including the following steps: T1: Turn off the timer Timer0, and then proceed to the next step; T2: Traverse and calculate the difference between the value of the field DataTime in the data records of the table Ship_XY and the current time of the local machine, and check whether this difference exceeds the set value MAX_TIME (unit: second, usually in the range of 1 to 1800, recommended to be set to 600). If it exceeds, delete this data record; T3: Traverse and check whether the values of the field Zone_No in the data records of the table Ship_XY are all greater than Z. If they are all greater than Z, send a control off instruction to the n LED information board devices, p marine flasher devices, and q marine warning horn devices, and then exit this interrupt service. Otherwise, proceed to the subsequent steps; T4: In the Ship_XY table, there are data records whose Zone_No value is less than Z+1. The microprocessor first loops through the RiskZone_Radio field ID=i with the risk zone number i (i=1~Z) to perform an associated search to obtain several data records. The retrieved records are read one by one, and the fields TXT, Type, and Rhythm are read. The voice type is determined by the Type field. The text in the TXT field is converted into voice at the frequency agreed in the Rhythm field and sent to the VHF radio module. Secondly, the risk zone number i is used to perform an associated search in the Dic_RiskZoneISM field ID=i. The field Zone_No=i and the field Device_Type=1 of the table RiskZone_Device and the field ID=i of the table RiskZone_LEDTXT are searched, the microprocessor reads the retrieved records one by one, reads the values ​​of the fields TXT, Color, Rhythm, and Device_ID of the table RiskZone_LEDTXT, constructs instructions according to the protocol, and sends them from the ISM transceiver module with the frequency band specified by the field ISM_Freq of the table Dic_RiskZoneISM; then the risk zone number i (i=1~Z) takes turns in the field ID=i of the table Dic_RiskZoneISM and the field Zone_No=i and the field Device_Type=2 of the table RiskZone_Device The microprocessor reads the retrieved records one by one, and constructs instructions according to the protocol with the values ​​of the fields Device_ID and On in the table RiskZone_Device, and sends them from the ISM transceiver module with the frequency band specified by the field ISM_Freq in the table Dic_RiskZoneISM; finally, the risk zone number i (i=1~Z) is used in turn in the fields ID=i in the table Dic_RiskZoneISM and the fields Zone_No=i and Device_Type=3 in the table RiskZone_Device. The field ID=i of table RiskZone_Horn is searched, and the microprocessor reads the retrieved records one by one, and constructs instructions according to the protocol using the values ​​of the field Rhythm of table RiskZone_Horn and the field Device_ID of table RiskZone_Device, and sends them from the ISM transceiver module using the frequency band specified by the field ISM_Freq of table Dic_RiskZoneISM.
